Specification of Letters Patent.

Patented Jan.6,1@14.

Application filed December 5, 1912. Serial No. 735,097.

To all whom it may concern:

Be it known that I, HENRY L. Fnnnis, a citizen of the United States, residing at Harvard, in the county of MIcIIenry and State of Illinois, have invented a new and useful Improvement in Stanchions, of which the following is a specification.

My invention relates to certain new and useful improvements in stanchions, and is fully described and explained in the specification and shown in the accompanying drawings, in which:

Figure 1 is a front elevation of the entire stanchion showing the same in place; Fig. 2 is a sectional view of the upper portion of the stanchion showing the parts in which the invention, more particularly, resides; Fig. 3 is a top plan of the upper part of the stanchion, and Fig. 1 is an elevation, showing the stanchion partially open.

Referring to the drawings, 5 is a hollow tube, preferably of oval cross-section, forming the top bar of the stanchion; 6 is the relatively-fixed side; 7 is the bottom, and 8 is the swinging-side of the stanchion. The relatively-fixed side 6 is made adjustable on the top and bottom bars, but in the present case no novelty is claimed from such construct-ion, except that the remainder of the construction is such that its adjustability is not interfered with.

9 is a vertical bolt extending through the top bar of the stanchion, the same serving to fix in position certain of the mechanism but, more especially, at this time it is to be noted that this bolt runs in a slot in a finger 10, which lies within the top bar and is pivoted at 11 on the swinging-side of the stanchion. The finger thus operates as a link to limit the outward movement of the swinging-side, as a guide whereby the side is always returned into position properly when the stanchion is closed, and as means, when the stanchion is closed, for preventing relative transverse movement between the upper part of the swinging-side and the top of the stanchion. The finger 10 has projecting from it a fork 12, which is adapted to engage the side of the front frame of the stall, for purposes which are well understood in this art.

13 is a casting secured to the top bar by the bolt 9, and serving as a pivotal support for a loop 14, the right-hand or free end of which is slightly curved up at 15 to slide over a shoulder 16 on the finger 10, the loop, as a whole, being adapted to drop over a projecting corner 17 on said finger. The operation of this loop is manifestly to hold the stanchion closed while in such engagement.

The present form of construction possesses certain desirable advantages. In the first place, the entire guiding mechanism which serves as a limiting stop for the swingingside of the stanchion, is inclosed in the top bar, so that the animal cannot engage the locking mechanism with its horn to disengage it, nor does the guiding and limiting mechanism or link afford any unnecessary angles for the collection of dirt. Furthermore, the loop is so arranged and disposed as to latch automatically on the free side of the stanchion when it swings up, and besides, and this point is of great consequence, the free end of the loop is in such position that it can readily be disengaged from the angle on the finger by the thumb of the operator, while the operator grasps with his hand the upper part of the side bar to swing it open. In this manner, there is provided a very simple locking mechanism with which it is possible to open the stanchion entirely by the manipulation of one hand. The practical importance of this will at once be evident to those skilled in the art.

I realize that considerable variation is possible in the details of construct-ion herein shown and described, and I do not intend by illustrating a single, specific or preferred form to limit my invention thereto, my intention being in the following claims to claim protection upon all the novelty there may be in my improved construction as broadly as the state of the art will permit.

I claim as new and desire to secure by Letters Patent 1. In combination, a stanchion top bar and a movable side-bar, a finger connected to the sidebar and running in a hollow of the top-bar, a pin extending through the hollow of the top-bar and a slot in the finger, for the purpose set forth, and means independent of the finger for looking the side-bar closed.

2. In combination in a stanchion, a hollow top bar and a swinging side bar, a finger pivotally connected to the side-bar and running in the top-bar, a pin in the adapted to be engaged by the thumb of the 10 top-bar extending through a slot in, the operator, for the purpose set forth.
